SPRlNG COUPLING-LINK.

SSECIFICATION forming part of Letters Patent No. 271,592, dated February 6, 1883,

Application filed October 12, 1882. (No model.)

T 0 all whom rt may concern Be it known that I, GEORGE A. BAKER, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful lmprovement in Spring Coupling-Links, of which the following is a specification.

The object of my invention is to provide a cheap, simple, convenient, and durable spring cou pling-link for ships anchor-chains, or for securing shrouds, booms,or other parts of the rigging,or for any purposes for which couplinglinks and similar devices have heretofore been employed and it consists in the construction, combination, and arrangement of the several parts of the device, as hereinafter more fully described, and set forth in the claim.

Figure 1 represents a side elevation of a coupling-link constructed according to myinvention. Fig. 2 represents a longitudinal section Fig. 3 represents a cross-section of the same. Figs. t and 5 represent details of construction and modification of the same.

A and B represent the two coupling-links, formed of rods of round or other suitable wrought-iron bent into oblong shape, leaving the two sides F parallel and of equal length, or as desired, being preferably of the form shown in Fig. 2, or bent mid-length, so as to form a portion ofthe link A of U-shape. Then the curved central portion or end, 0, ofthe link I place in a suitable mold and cast therein the head portion D, having formed therein on opposite sides thereof suitable grooves, E E, adapt ed to receive therein the two sides F of a similar-constructed link, B, which is likewise provided with a cast head portion, 1), having formed therein on opposite sides thereof corresponding grooves, E E, which are adapted to receive therein the sides F F of the said link between the said heads DD is provided with a series of elastic or rubber disks,H,provided upon their peripheries with four transverse or lateral grooves, L, adapted to fit or receive the said sides F of the said links A B, and between the said rubber disks H are placedmetal disks P of similar shape,and likewise provided with grooves which tit loosely between the said sides F 'F of the said links, so as to form a compression-spring. The sections or disks of rubber H and intervening metal plates or disks, P, prevent the rubber from flowing or bulging, when pressure is bronghtto bear upon the same, by compression througli the links and heads being drawn or forced in opposite directions by the weight or strain brought to bear upon the same when in use.

Itwill be evident that the ends of the said 'lin ks A B may be formed with eyes, and a bolt ceive the bent or loop portion G of the link, as

shown in Fig. 5,in which case the heads are ing themin such position byineans of a central rod, as heretofore practiced.

I am well aware that spring-links are wellknown devices heretofore employed in connection with harnesses and draft devices. Therefore I do not broadly claim suchas my invention.

Having thus described my invention, what I claim is- In a spring coupling-link, the continuous or ICU welded link A, having the head D, provided I P, provided upon their edges with grooves with grooves E upon opposite sides thereof, which receive the sides of the links, suhstan- [o and the link B, having the head D, provided tially as described, and for the purposes set with grooves E upon opposite sides thereof, forth.

said grooves being adapted to guide and re- GEORGE BAKER. tain the said links in position with each other, Witnesses: and the central compression-spring composed SYLVENUs \VALKER,
